Looking for a 20 pole generator

[rleonard]

I am looking for a 20 pole "pancake" alternator.  This would to be direct driven by a RH engine.  Needle in a haystack I know, but you guys are far reaching and quite resourceful.  These were used in mines, driven by steam engines, or as a part of a hydro-electric system.  A motor would be acceptable as I could turn it into a generator.
